RUSH
Amazing musicianship, tightness, intriguing lyrics, just to name a few. the complexity and technicality of their music is matched by NO ONE. Neil Peart is the number one rock drummer in the world (its a fact, go look it up), and he also writes the lyrics. Rush makes rock music so much more respectable and intelligent than anyone. plus they are all in their 50's right now and are still touring/putting out new music that is awesome. they've been around for over 30 years, and that is a fantastic achievement in itself. There are only 3 of them, and they make their music sound like there are 5 or 6 of them. All 3 of the guys have to do so much up there, not just playing their main instruments, but playing foot pedals to trigger other parts, playing keyboards/MIDI controllers, and even Neil uses electronic drums to recreate sounds on their albums that would be impossible otherwise.

And if you can't stand his voice (you have to learn to love it imo), then here's an instrumental, "Leave That Thing Alone":
